I haven't really watched a lot of the twins. I like Elliott's take on fitness, that he doesn't just give you a workout, I take most of it with a grain of salt but all his fitness stuff is impressive and helpful. I personally like Jeff Cavalier as well, I think he's like JdCav or something on YouTube, athleanX is his system he gives away towns of free workouts but sometimes it gets a little too "new age" for me, where he's standing on a ball with one leg and leg curling with the other while doing rows and crunches at the same time.
